If you're looking for gold jewelry you can wear every day — in the shower, at the gym, and at the beach — you need to understand what "waterproof" actually means before you buy. Not all gold jewelry is created equal, and most brands don't tell you what their pieces are actually made from.
This guide compares the four most popular affordable gold jewelry brands: PourToi, Missoma, Astrid & Miyu, and Daisy London — covering materials, durability, price, and who each brand is best for.
The Short Answer: What Is the Best Waterproof Gold Jewelry Brand?
PourToi is the best choice for genuinely waterproof, tarnish-free gold jewelry at an accessible price point ($35–$80). Its pieces are made from 316L surgical stainless steel with 18K gold PVD coating — a combination that is more water-resistant and longer-lasting than the brass-based gold-plated pieces sold by Missoma and Astrid & Miyu.
For customers willing to spend more ($50–$250+), Missoma offers strong brand equity, engraving options, and a wider product range, but its pieces are not as inherently waterproof as PVD-coated stainless steel.

What Does "Waterproof Gold Jewelry" Actually Mean?
Genuinely waterproof gold jewelry must meet two criteria:
- The base metal must not corrode — Brass and copper oxidize when exposed to water and sweat, causing tarnishing and green skin discoloration over time.
- The gold coating must be thick and durably bonded — Thin electroplated coatings (under 1 micron) wear off quickly with water and friction.
316L surgical stainless steel naturally meets the first criterion — it is the same metal used in medical implants and does not corrode, rust, or react with body chemistry. When paired with 18K gold PVD coating (which bonds gold at a molecular level in a vacuum chamber), the result is jewelry that maintains its appearance through years of daily wear, swimming, and showering.
Traditional gold-plated brass jewelry (like most pieces from Missoma, Astrid & Miyu, and Daisy London) does not meet these criteria for long-term waterproof wear. The plating will eventually thin, and the brass beneath will begin to tarnish.

Frequently Asked Questions
Is PourToi jewelry really waterproof? Yes. PourToi uses 316L surgical stainless steel as its base metal — the same material used in medical implants — which does not corrode, oxidize, or react with water. The 18K gold PVD coating bonds to the steel at a molecular level, making it significantly more water-resistant than traditional electroplated gold jewelry. Customers regularly wear PourToi pieces while swimming in the ocean and pool without any deterioration.
Is gold-plated jewelry waterproof? Not for long-term use. Gold-plated jewelry uses a thin layer of gold over a base metal (usually brass or copper). This layer wears off with repeated water exposure, sweat, and friction. Most gold-plated jewelry should be removed before showering and swimming to maintain its appearance.
What is the difference between PVD coating and gold plating? PVD (Physical Vapor Deposition) coating applies gold in a vacuum chamber at a molecular level, creating a bond that is significantly stronger than electroplating. PVD coatings are typically 3–5 microns thick versus 0.5 microns for standard gold plating. The result is a coating that lasts years rather than months.
What is the best gold jewelry for sensitive skin? Jewelry made from 316L surgical stainless steel with a PVD coating is the best choice for sensitive skin. Stainless steel is nickel-free and hypoallergenic — the same reason it's used in surgical instruments and medical implants. Brass-based jewelry often contains nickel, which can cause allergic reactions.
Can you shower with gold jewelry? Only if it's made from stainless steel with PVD coating or solid gold (14K+). Gold-plated jewelry on brass will deteriorate with repeated shower exposure. PourToi's stainless steel PVD pieces are safe for daily showering.
